The KRISS Vector SDP-SB Enhanced is the most versatile version of the Vector SDP. The addition of the MK5 Modular Rail offers more picatinny rail space for accessories. Between the receiver and the arm brace tube is the KRISS Ambidextrous Folding Adaptor, which cuts the overall length of the Vector SDP-SB Enhanced by more than seven inches when folded.

At the heart of the Vector SDP-SB Enhanced is the Super V System, a nonlinear, multilink, blowback system designed to redirect recoil energy down. The Super V System in conjunction with the low bore axis reduce felt recoil and muzzle climb. Like all KRISS Vector firearms, the SDP is fed with full size Glock® magazines, offering cross compatibility of ammunition for a secondary or back up hand gun.
